\section{Concept}
Based on the hypothesis: \textit{“If the existing virtual experience at Koldinghus is enhanced with soundscapes, the user will be motivated to interact with the system for a longer period of time.” }

In order to establish if the hypothesis is true, it was decided to create fields of interest based on sounds, that would enrich the viewers experience by expanding the visual part to encompass a soundscape. It is believed, that the addition of sound will make the user spend more time using the application, because of the added interactivity.

The concept outline consists of giving the user another level of immersion by setting a soundstage, that brings the user back to the original chapel as visually depicted by the existing application.
The user will be presented with sound inputs that will mimic the position of the tablet. When the user interacts with the device, the areas of interest will “light” up when panned over, thus enabling the user to perceive that this area stands out compared to the surroundings. 

\textbf{Example scenario:} \newline
The user picks up the tablet and puts on the headphones. The user will see the visual historic world through the tablet and hear a combination of the all the sound fields, which should mimic the initial position of the tablet and give the user a fictional position in the middle of the room amongst the crowd. The user will then start to move the tablet around to view the church, operating the tablet as normal. While this interaction takes place, the sound fields will increase or decrease depending on the users movement directions. If, for example, the user aims the tablet towards the seat of the priest, the predominant sound input will be of the priests sermon. The user will be able to detect several other sound fields while moving the tablet around; a choir singing when directing the tablet towards the upper gallery and an organ playing towards the back end of the gallery.
